r o ad 'whom t may concern:

Be 'Vit known that WAI/rmi M. INGRAM, a citizen of the United States,residing at Baltimore, in the State .of Maryland, have invented certainnew and useful Improvements in Joints, of which the following is laspecification, reference being had I therein to the accompanyingdrawings.

This-invention relates to joints and Xhas for an object to provide ajoint of improvedring grooves with'a Wire.extendingJ about said grooves'with' improved means for disassoclating the wire from its associatedgrooves.

A further objectfof Ithe invention is` to provide a joint fon a' tubularmember and an inclosedcylindrical member, said joint comprisingregistering 'grooves formed in the `contacting parts of the members of.such proportion as to receive a wire about and to initiate 'theunlocking.

withinqsald grooves with improved means for insuring the lmovement ofthe end' of said wire outwardl for the purpose of un lookin the parts.i" i Wit these and other objects-in view, 'the invention ,comprisescertain Vnovel units, parts, combinations, functions and mechanicalmovements ash willi be hereinafter more fully described' and claimed.'In the drawing: Figure 1 is a view in.` side 'elevation of a tubularmember showingin side elevation the joint associated therewith. :Figure2 is a. transverse sectional View through the joint: on 4the planeindicated by line 2-2 of Figure `.1. l

Figure 3 is a view taken onthe same .plane as Figure 2` with the partsrotated to position to partlylock or partly unlock the joint.

cor-

The. improved jena what forms the Subthis application -is adapted tolock a pipe or tube 10to a cylindrical member 'which will it therein,'which said cylindrical member may' be rthe head indicated at 11 or, ofcourse, any cylindrical member, tubular or otherwise which will fitwithin the tube 10.i The tube 10 is provided with a groove 12',preferably formed by striking up a bead 13 at-some position spaced apredetermined' distance from the f,

end. 4of said' tubular member.y

The bead in the type of joint shown at Figures L to 5 inclusive is.,interrupted by4 )oeing cuties indicatedfat 14 and the interiorcylindrical member is provided with a 15n atl such piiint as to registerwith groove the roove 12. '.']i`hi`s Yregistry may be v1n` sure byproviding the cylindrical'member with a' shoulder 16, lalthough it isobvious, of course', that such shoulder is not essen- `tial t theinvention. The cylindrical memradial` socket .17 into which the rightangularly turned extremity 18 of the wire 19 isv Byy inserting the`right angular 4loer is `also' provided with. a substantially,

end 18 inthe socket`17 when said socket is registering with the' opening14 and by turning the member 11, the wire 19 may be Wound into theregistering grooves 12 an`d-i5.- Adjacent the socket 17,' the grove'l isout upon a' cord as indicated :ii-@20, forming; afulcrum point21overwhich the end 220i thewire will bend as indicated more par.- 5

ticularly .at Figure 2 and. frommliich it wili" roo spring'boutwardlytlirough the opening 1e cated'at Figure L5- when the parts arethe purpose'of unlocking the parts.

-It will, herefore, vbe apparent that starting with the membersjas shownat Figure 2 crum point 21 as shown at Figure 5 where; upon a continuedunwindingi the direction l indicated by the arrow at Figure 3 will serveto feed the wire out of the opening 1,4 so that, when the 'socket 17again registers with the opening 14, thewwire may be wholly removed fromengagement lwith the partsv andthe parts themselves disassociatedp r Thetype shown'at Figures 6 to \8 inclusive comprisesa groove 23 out intothe cylindrical member 24 of lsuch depth that rthe Wire 25b ma bewhollycontained therein, while the cy indrical member 24:'is' being in sertedin the .tube l0. A passage is provided .i

.from a wedge member l26 which is driven between the extremities of thewirei25, expanding such wire-,25 to the position shown at Figures 7 and8, that is to say expanded into the Ogroove 12 and preventing therebythe removal of the part 24: therefrom. The

l wire 25' will preferably be composed of y tract so that, w

s rin u material havin a tendenc to conr/ P g il g y withdrawn, the wirelwill automatically ycontract to clear the groove 12 removal of thehead24C.

What l claim is? f 1. A joint for a /pipe and a contained cylindricalmember comprising the formatlonhin said pipe 'of an interior.circumferential groove and Jili the cylindrical member an exterior.`groove registering with the vgroove of the pipe, said groove comprisina radial socket4 and a chordal'portion a jacent said radiallsocket, thematerial of said pipe being cut throii'gh. at one point permittingtheinsertion therethrough vofthe exen the wedgeimember 26 isl and permitthe signature in presence '1% iaeaaee tremity .of a wire `to-occupy theregistering grooves and to bendv downwardly over the,

chordal part of the-groove V'.in -said cylindrical member.

2. A jointfor a tube and a contained cylindrical member provided/ withregistex-,

out through to give. access o said groove,

ing circumferential groovesktsiid tube being and the vgroove of thecylin rical member being formed at one. pointes the cord of a,

access Afrom the'exterio and a Wire having 'a right angular extremityproportioned to be inserted in said socket and wound into saidregistering groove by the rotationx'of the parts relatlve toeach otherwith ap extremity bent vdownwardly over tlie angle formed by the cordand-'adapted thereby to spring outwardly through the opening in thetubular member, y
